GFDM Asynchronous burst transmissions. Block based structure. Can be set to mimic CP-OFDM. Proved support for High-order modulation (HOM) and Tactile Internet. In contrast to CP-OFDM, it can benefit from transmitting multiple symbols per sub-carrier. Reduced OOB emissions due to adjustable pulse shaping filters. Relax the current requisites of oscillator accuracy of 0.1 ppm in LTE up to 10-100 times (1-10 ppm). Dismisses complex synchronization procedures and reduces signaling overhead, i.e., of simpler transmitters. Allows equalization in the frequency domain. Favorable to short burst applications. Contributes to reduce the power consumption of the terminals. UFMC Differently from CP-OFDM, which applies filtering on the whole band, UFMC applies filtering on a per resource block basis. Higher spectral efficiency and robustness against time and frequency offsets when compared to CP-OFDM. In case of fragmented spectrum, UFMC supports non-contiguous sub-bands. Highly reduced OOB emissions. Short filter lengths, which implies in low latency. Reduced overhead. Improved MTC support. Very efficient to transmit both long sequences and short bursts/frames. FBMC Excellent frequency localization. CP can be removed and subcarriers can be better localized, thanks to more advanced prototype filter design. Instead of digitally filtering the complete band, the modulator includes a filtering functionality on a per subcarrier basis. FBMC does not employ a CP, which results in high time-frequency efficiency. FBMC is not orthogonal with respect to the complex plane. OQAM is used to attain orthogonality. Very efficient to transmit long sequences however it suffers to transmit short bursts/frames. BFDM Replaces orthogonality of the set of transmit and receive pulses by biorthogonality, which is a weaker form of orthogonality. Well suited to sporadic traffic, since the PRACH symbols are relatively long so that transmission is very robust. It is well suited to be used in the random access scenario (PRACH). Can exploit the capabilities of advanced sparsity-aware signal processing. Robust to frequency offsets in the transmission which, as well-known, typically sets a limit to the symbol duration in CP-OFDM transmission. Completely asynchronous users, with time offsets larger than the CP duration in standard PRACH can be far better supported. Excellent and controllable tradeoff between performance degradation due to time and frequency offsets. Leads to a slightly reduced interference in PUSCH when using (previously unused) guard bands for data transmission. DFT-s-OFDM Replaces the CP with a set of very low power samples (zero-tail). Zero-tail can be set according to the estimated delay spread of the channel without compromising symbol length. Preserves the orthogonality of the data subcarriers at the receiver. Low implementation complexity (approximately the same when compared to a LTE transceiver). Significantly lower OOB emissions than CP-OFDM. Lower PAPR than CP-OFDM. Enables coexistence among systems designed for different environments (e.g., indoor/outdoor).

Major Goals o Review and analysis of the satellite connection to service the 5G networks within the
context emerging technologies: SDN, NFV, CDN, ICN, and IDN. o Study of terrestrial-satellite interoperability to service the 5G networks within the
context of: (i) emerging techs; (ii) content distribution in multicast networks; (iii) aeronautical and maritime applications.
o Contributing to 3GPP standardization process to include satellite links in all aspects.
Preliminary Results o 5G to be built from terrestrial-satellite convergence, rather than separate networks. o 5G standardization should contemplate hybrid architecture. o Interoperability and integration of satellite links to 5G is a key requirement, with no
mooring or patching.
